My invention relates to improvements in tie wire fasteners and keys-and it consists in the combinations, constructions and-arrange ments hereinafter described and claimed.

B An object of my invention is to provide a tie wire fastener and key that is designed especially for securing wall board to a metal stud for providing a hollow wall construction. The tie wire fastener has openings for I the wire that are inclined with respect to the axis of the wire. This causes the fastener to grip the wire.

The tie wire fastener, in conjunction with the tie wire, provides a key for holding plas- 1 ter to the wall board. The tie wire is bent so as to have its endengage with the fastener, and the bent portion provides a spacebetween the wire and thefastener which receives plaster. In this way the device acts as a key for the plaster. I

A further object of my invention is to provide a device of the type described which is extremely simple in construction and which cuts down the amount of time re- 2 quired to secure wall board to the studs. The means used in bending the tie wire into place also pulls the wire taut, and thisinsures a firm connection between the stud and the wall boards. here fibrous wall boards or plaster boards are used, the fastener acts as a washer for preventing the wire from becoming embedded in the wall board, which would result in the loosening of the construction.

Other objects and advantages will appear as the specification proceeds, and the novel features will be particularly pointed out in the claims hereto attached;

My invention is illustrated in the accompanying drawing, in which:

Figure 1 is a front elevation of the device,

Figure 2 is a section along the line 52- 2 of Figure 1, V V Figure 3 is a perspective view of the fastener,

Figures 4 and 5 show how the tie'wire is secured in place,

Figure 6 is a sectional view of a modified form of. the device, 7 Figure 7 is a plan view of Figure 6,

Figure 8 is a longitudinal section through the form of fastener shown in Figure 8 v In carrying out my in vention', I providea plurality of metal studs 1 that have openings Q'therein. I

' Va li hoards 3 formed of compressed fibrous material or wall board are disposed on either sid'eof the studs and are locked'to the studs in a manner now to be described. I

I force a tie wire 4: of the shape shown in Figure 5 through one of the plaster boards 3, then through the aligned openings 2 2, and 1 then through the opposite plaster board When the wire is first forced into place, it has a bent end 5' and a straight end portion G. fastener? of the shape shown in Figure is first mounted upon the wire t prior to its entrance into the plaster boards. The bent end 5 is inserted in a recess 8 in the upturned portion 9' of the fastener 7. The'tie 71;) wire 4 passes through an opening 10' inthe fastener 7, and it will be noted from Figure 3 that thisopening isinclined away from the recess 8..

From the description thus far, the wireand a5 fastener? willtake the appearance shown in Figure 4'. Asimilar fastener '7 is now applied to the other-end of the wire. The openinglO in this fastener is such as to tend to prevent movement of the tie wire with respect to the so fastenerwhen the fastener extends at right angles thereto. The operator in securing the other end-of the tie wire in place, grips the projecting end portion 60f the tie wire with pliersindicatedgenerally at Hand rocks the pliers into the dotted line position shown in Figure 4. The pliers have a blunt jaiw end .12, and therefore the'rocking of the pliers in a clockwise direction will pull the tie wire a taut and will press the Wall board '3 firmly .90 against the metal stud 1 and the fastener 7 against thewall board. This pulling of. a slight portion of the wire through the opening 10 at the same time the portion 6 of the wireisbent into the position A shown in Figures' 4 and 5 .will securely fasten all of the parts together and will prevent the slipping of the fasteners on the wires. Afterthe por- "tion6 has been bent into the position A, itmay be furtherbent into the position B shown'in' Figure 5 and also shown in Figure 2. In the position B the portion 6 is received in the recess 8 of the fastener 7 The parts are now securely locked together. a

The recesses 8 in the fasteners 7 prevent rotation of the tie wire 4 with respect to the fastener 7 ,andin this way the edges of the inclined openings 10 frictionally engage with the tie wire 4 and prevent slippage between the tie .wire and the fasteners. The fasteners also prevent the relatively thin tie wire from having its ends 5 and 6 become embedded in the fiber or plaster board 3 and thus loosen the connection between the boards and the metal stud 1.

.The co-action between the fastener 7 and the ends of the tie wire provide a key for the plaster which will form a lock between the plaster 12 and the wall board 3. It will be noted from Figures 2 and 4 that a space 13 is provided between the bent ends of the tie wire and the fastener members 7. ,Thisspac'e receives the plaster while the plaster is still in a plastic state. Whenthe plaster hardens,

the ends 5 and 6 will be embedded in the.

plaster, and in this way the device actsas a key for locking the plaster to the boards. In

Figure 1, I show two of the devices, the lower one being embedded in the paster 12 while the upper one is shown bearing against the plaster board 3, the plaster being removed from the upper one for clarity. Thedevice is extremely simple in construction, and performs a number of functions.

. In Figures 6 and 7, I show a slightly modified form of the device. The fastener in I this form of the device consists ofa flat-piece of metal without any turned-up portion. The piece of metal 25 has a recess 26 therein that corresponds with the recess 8.

- f The tie wire 27 has a curved portion 28 disposed at one end, and the plane of this curved portion ext-ends at right angles to the axis of the wire. The curved portion acts as a head and abuts against the plaster board 3.

The other end of the tie wire isnpassed through an inclined opening 29 in the plate 25 similar to the opening 10, and the end of the wire is bent over by means of the pliers in the same manner as the end 6 of the wire 4 is bent into the position A. The bent end 30 is then hammered down so as to be received within the recess 26. The end 30 and the fastener 25 form a'key for the plaster. The other parts of the device are the same as that already set forth, and similar reference numerals will therefore 'be applied to these parts. 7 V a p e Although I have shown and described two embodiments of my invention, it'is tobe understood that the same is susceptible of various changes, and I reserve the, right to employ such changes as may come within the scope of the invention as claimed..-
